Science & Benefits

Methionine is a sulfur-rich essential amino acid that acts as a powerful antioxidant and metal chelator. It protects skin cells from environmental pollutants and oxidative damage. As a humectant, it binds water to the stratum corneum. It is zero-comedogenic and zero-irritant. Its logic in acne care is the prevention of 'lipid peroxidation'—it stops sebum from turning into pore-clogging 'wax,' maintaining skin clarity while delivering hydration.
